A few things
worth knowing.
Do I need an account?
No. Every tool on this site is available without creating an account or signing in.
Are my files uploaded anywhere?
No. Conversion, checksum calculation, formatting, and encoding use browser features on your device. The website serves application files, but your selected files and text are not sent to our server.
Which image formats are supported?
PNG, JPEG, and WebP. Conversion uses your browser's image support. Animated images and specialized formats are not supported.
Why is there a file-size limit for checksums?
The checksum utility uses the browser's memory. A 100 MB limit reduces the chance of memory problems on phones and older computers.
Can I use these tools on mobile?
Yes. The workspace is responsive and uses standard browser APIs. Some features depend on what your browser supports.
